In 1817, the Scottish optical scientist David Brewster submitted a patent for a kaleidoscope, a word he invented. It went on to great success within only a few years, spreading the word far and wide. But where did Brewster get the word from? He created it from joining two Greek words: kalos, meaning "beautiful", and eidos, meaning "shape", obviously so named because of the pretty patterns formed when one looks through a kaleidoscope (additionally, -scope is just a suffix, influenced by telescope, meaning "examine"). Kalos sounded something like kalwos in what was most likely Proto-Hellenic, and in Proto-Indo-European it took the form of kal, also defined as "beautiful". Meanwhile, eidos derives from the reconstructed PIE root weydos, meaning "to see" (this developed from "shape" to "image" over time before ultimately settling on that).

Hello! I'm Adam Aleksic. This year, I graduated from Harvard University with a degree in Government and Linguistics. There, I co-founded the Harvard Undergraduate Linguistics Society and wrote a thesis on Serbo-Croatian language policy, magna cum laude. In addition to etymology, I also really enjoy trivia, politics, vexillology, geography, board games, conlanging, art history, and law.
